Equimins Sand-Ex Pellets is an all-natural dietary pelleted fibre supplement, containing psyllium (plantago ovata) combined with probiotics and prebiotics. It is designed for use when sand is in the intestinal canal, acting as a natural fibre and microbial supplement to greatly assist the natural flow of food through the intestinal tract. Being pelleted means this product can be swallowed easily and does not turn to jelly until it is in the digestive system.
